guys and dolls.

One thing I've come to suspect over the years is that men are fairly binary in their decision making processes.

Ergo:

If a guy really wants a beer, he gets up off his ass and gets a beer.

If a guy doesn't really want a beer, he doesn't bother to get off his ass and get a beer.

Likewise:

If a guy really wants the girl, he gets up off his ass and gets the girl.

If a guy doesn't really want the girl, he doesn't bother to get off his ass and get the girl.

This is only a working theory, but I'm pretty sure this is Occam's Razor for Relationship Dummies.

Or, for Smart Dummies:

entia non sunt multiplicanda praeter necessitatem.
